METALLIC FASTEN FOR WINDOW-PANES.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application iIed February 5, 1915. Serial No. 6,295.

To all 'whom t may concern Be it known that I, LEE W. KENNARD, a citizen of the United States, and a resident of Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Metallic Fasteners for Window-Panes, of which the following is a description.

The invention relates to improvements in metallic window pane fasteners, such as are employed in mounting large lights in win`` dow frames.

More particularly, it relates to fasteners of that type in which a fixed member is secured to the window frame to form a seat for the pane, and a movable member is provided for clamping the pane to the fixed member to hold the light in its seat.

It has for its object the provision of a fastening device that can be readily applied and which will firmly hold the pane in place, and one that will accommodate panes of different thicknesses.

The invention consists in a device of the novel construction, combination and arrangement of parts hereinafter described, pointed out in the appended claims, and illustrated by the accompanying drawings.

In the drawings, in which similar reference characters designate corresponding parts, Figure 1 is a perspective view of a' section of a fastener embodying the invention. Fig. 2 is a perspective view of the fixed member of the fastener. Fig. 3 is a perspective view of the movable member. Fig. 4 is a horizontal sectional view through the fastener. Fig. 5 is a cross sectional view l through the fastener.

In the drawings only a' section of the fastener is shown as applied to the bottom rail ofa window frame. It is to be understood, however, that the same construction extends around the entire frame to hold the light in place. Each of the two members of the fastener is formed of sheet metal, bent and shaped to give the required formation.

The lower rail of the window frame comprises the base 1 and the offset 2 projecting upwardly from the base. To the outer face of the offset is secured the fixed member of the fastener comprising the vertical back 3 and the approximately horizontal shelves 4 and 5 respectively projecting outwardly from the upper and lower edges of the back. The back 3 abuts the upper part of the offset 2 with the upper shelf 4 Hush with the top of the offset, and the lower shelf 5 a considerable distance above the base 1. Screws 6 passing through the back 3 hold the lixed member in place on the offset. Extending downwardly from the outer edge of the upper shelf 4 is the flange 7 to form a backing against which is placed the inner face of the window light 8. Extending longitudinally along the upper face of the upper shelf 4 is the gutter 9 to catch the dripping from the inner face of the light. At intervals along the gutter arethe openings 10 through the upper shelf through which the dripping escapes onto the lower shelf.

The lower shelf 5 of the fixed member projects outwardly from the lower edge of the back 3 and forms the rest for the lower edge of the window light. Thev inner side of the lower shelf is slightly inclined downward to the horizontal seat 11 on which rests the lowerv edge of the light. Interposed between the seat and the edge of the glass is the cushion 12 to form an even rest for the light and to take up any jars to which the light might be subjected. The outer side of the lower shelf projects a considerable distance beyond the seat 11 and is formed into a double flange by folding the sheet metal back on itself. Beneath the flange the metal is bent downward to formthe vertical brace 13 to support the lower shelf. TheV lower edge of the brace is bent inward at right angles to form a foot 14 that rests on the base 1 of the window frame. v'Ihe brace 13 is almost directly below the seat 11 so as to uplport the shelf beneath the weight of the 1g t. one, auxiliary supports 15, in the shape of blocks, are placed at intervals beneath the seat 11 to aid in the support of the pane.`

Should the glass be comparatively light in weight the blocks would not be needed, neither would the blocks be needed along the side and upperedges of theA pane even when the glass is heavy. The brace 13 and the foot 14 are cut away, at intervals to form in the fixed member the comparatively deep opening 16 and the comparatively shallow slot 17 leading from the opening to receive the clamping parts of the movable member of the fastener as hereinafter described.

The movable member of the fastener comprises the front 16, shaped to give an ornamental appearance, which has projecting inward from its upper edge the upper horizontal shelf 17. The inner edge of this Should the pane be an extra heavy.

shelf is bent downward to form a fiange 18 that bears against the outer face of the pane opposite to the flange 7 of the fixed member when the movable member is in place. The two flanges 7 and 18 clamp the pane on opposite sides and hold it firmly in place.

Projecting inwardly from the lower edge of the front 16 is the lower horizontal shelf 19 that rests on the base 1 when the movable 'member of the fastener is in place. The inner edge of the shelf 19 extends beneath the outer edge of the shelf 5. Extending along the inner' edge of the shelf 19 is the rib 2G forming with the front 16 a gutter that will receive the dripping falling over the outer edge of the shelf 5. This rib 20 also forms a longitudinal stiffening for the shelf 19. At intervals in the lower edge of the front 16 are the openings 21 to drain the gutter in the shelf 19. The cushion 12 can be cut away at intervals so that the dripping can readily pass beneath the pane over the shelf 5 into the gutter of the shelf 19. The openings 10 and 21 not only facilitate the drainage of the dripping from the inner face of the pane, but they will also ventilate the interior of the fastener to prevent rust of the metal and decay of the wood.

On the rear edge of the shelf 19 are the clamps for clamping the movable member of the fastener to the fixed member. Each one of these clamps consists of the horizontal plate 22 projecting from the rear edge of the shelf and having an upturned flange 23 extending at an acute angle to the longitudinal edge of the movable member to form a bevel bearing.

After the light 8 has been positioned on the seat 11 of the fixed member of the fastener and against the backing 7 the movable member is placed on the base 1 of the window frame with the plate 22 and the -bevel bearing 23 of each clamp opposite to one of the large openings 16 in the fixed member. The movable member is then moved inwardly and longitudinally, (to the right as shown in Fig. 4) so that the plate 22 and the bevel flange 23 will enter the opening 16 in the plate. As the movable member is moved longitudinally the bevel bearing rides over the edge 211 ofthe fixed member and forces the two members together to clamp the light 8 between the backinCr 7 and the flange 18. The slot or opening 1% permits the plate 22 to enter the fixed member. As the bevel bearing 23 has considerable length there can be considerable variation in the width of the gripping action of the jaws formed by the backing 7 and the flange 18, so that the fastener can be used in mounting lights of different thicknesses. After the movable member has been adjusted to the clamping position, it is held in place against longitudinal movement by the screw 25 passing through the movable member into the window frame.

Ordinarily this screw will not be needed as the ornamental corner piece that is used to cover the ends of the fasteners will be sufiicient to hold the movable member against longitudinal movement.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: Y

1. In a metallic fastener for window panes, a fixed member comprising` a back and two shelves projecting outwardly from the back with one of the shelves forming a seat for the edge of the pane and the other shelf forming a backing to abut the inner face of the pane, and a brace beneath the shelf forming the seat to support the weight ofthe pane, said brace being cut away at intervals to form clamp openings; a movable member comprising a front, a fiange projecting inwardly from the top of the front to hold the pane against the backing formed by the shelf of the fixed member, and a shelf projecting inwardly from the bottom of the front to vform a seat for the movable member; and a series of clamps on the movable member for clamping the latter to the fixed member, each of said clamps comprising a plate having a bevel bearing operating to enter an opening in the brace of the fixed member so that the bevel bearing by engaging the adjacent edge of the brace will force the two members together as the movable member is moved longitudinally along the fixed member.

2. In a metallic fastener for window panes, a fixed member comprising a back and two shelves projecting outwardly from the back with one of the shelves forming a seat for the edge of the pane and the other shelf forming a backing to abut the inner face of the pane, and a( brace beneath the shelf forming the seat to support the thrust of the pane, said brace being cut away at intervals to form clamp openings; a movable member comprising al front, a flange projecting inwardly from the top of the front to hold the pane against the backing formed by the shelf of the fixed member, and a shelf projecting inwardly from the bottom of the front to form a seat for the movable member, a stiffening rib extending along the inner edge of the shelf forming the seat for the movable member; and a series of clamps on the movable member for clamping the latter to the fixed member, each of said clamps comprising a plate projecting inwardly from the lstiening rib and having on its inner edge a bevel bearing operating to enter one of the 'openings in the brace of the fixed member so that the bevel bearing by engaging the adjacent edge of the brace will force the two members together as the movable member is moved longitudinally along the fixed member.

3. In a metallic fastener for window panes, fixed and movable members for engaging the edge of the pane, said fixed member 4being cut aWay at intervals to form a comparatively deep opening and a comparatively shallow slot leading from the deep opening, and a series of clamps for holding together the fixed and movable members, each of said clamps comprising a plate projecting from the movable member and a iange on the plate extending at an acute angle to the longitudinal edge of the movable member, said plate operating to enter the opening and slot in the fixed member and the ange operating to enter the opening to engage the adjacent edge of the fixed 15 member to force'together the two members as the movable member is moved longitudinally along the fixed member.
